Implementations§
source§impl DepNode
impl DepNode
sourcepub fn new_no_params<Tcx>(tcx: Tcx, kind: DepKind) -> DepNodewhere
Tcx: DepContext,
pub fn new_no_params<Tcx>(tcx: Tcx, kind: DepKind) -> DepNodewhere
Tcx: DepContext,
Creates a new, parameterless DepNode. This method will assert that the DepNode corresponding to the given DepKind actually does not require any parameters.
pub fn construct<Tcx, Key>(tcx: Tcx, kind: DepKind, arg: &Key) -> DepNodewhere
Tcx: DepContext,
Key: DepNodeParams<Tcx>,
sourcepub fn from_def_path_hash<Tcx>(
tcx: Tcx,
def_path_hash: DefPathHash,
kind: DepKind,
) -> DepNodewhere
Tcx: DepContext,
pub fn from_def_path_hash<Tcx>(
tcx: Tcx,
def_path_hash: DefPathHash,
kind: DepKind,
) -> DepNodewhere
Tcx: DepContext,
Construct a DepNode from the given DepKind and DefPathHash. This method will assert that the given DepKind actually requires a single DefId/DefPathHash parameter.

source§fn extract_def_id(&self, tcx: TyCtxt<'_>) -> Option<DefId>
fn extract_def_id(&self, tcx: TyCtxt<'_>) -> Option<DefId>
Extracts the DefId corresponding to this DepNode. This will work if two conditions are met:
- The Fingerprint of the DepNode actually is a DefPathHash, and
- the item that the DefPath refers to exists in the current tcx.
Condition (1) is determined by the DepKind variant of the DepNode. Condition (2) might not be fulfilled if a DepNode refers to something from the previous compilation session that has been removed.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
